Parker is planning to build a playhouse for his sister.The scaled model below gives the reduced measures for width and height. H
kipiarov [429]

Answer:

The cross multiplication would be 10(350) = 22(x).

Step-by-step explanation:

We would first convert meters to centimeters.  There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.

The ratio of the height to base of the model is 10/22.  The ratio of the playhouse would then be x/350.  This gives us

10/22 = x/350

Cross multiplying, we would have 10(350) = 22(x).

Simplify.<br> 2 ( w + 3 ) - 4w<br><br> = ? ?
DENIUS [597]
Okay, so let’s work this out.

We have to use the distributive property to get rid of the parenthesis.

Multiply the 2 by each thing inside of the parenthesis

2 ( w + 3 ) - 4w

2w + 6 - 4w

Add Like Terms (w)

-2w + 6

Now I am not sure whether you are just simplifying the equation or solving for w, so make sure to be more clear about that next time.

I simplified the problem, so you should be able to take it from here.
